Website blocked due to Trojan constant message popup

[djlane1]

Hi,

MWB and Defender are both showing the system as clean, (I used MWB to remove the threats today) but the message pops up every minute or so.

Sometimes it just says outbound, sometimes (rarely) it mentions c:/windows/explorer.exe.

thanks in advance

Do the popups only happen when your default Browser (Chrome) is running..?

Edited September 28, 2018 by kevinf80
typing error

[djlane1]

No - the popups start immediately after booting, before any browser is opened.

I have turned off MWB notifications, but presumably my system is still infected with something that's causing the browser to open the website.

thanks

Hi Kevin,

2 file attached.

One shows malware on CUH.exe, and I have now deleted that file. I don't need the updater anyway.

I turned off MWB notifications last week so not really sure what's happening "behind the scenes".  

Turned on notifications again and seems I have only three  "website blocked" messages today, whereas i had on every minute or so when I started this thread.

Anything else i should do ?

thanks..

 

[kevinf80]

Can you post those website blocked logs..

[djlane1]

See attached Kevin.

 

2 reports yesterday (both identical so I only posted 1), none today so far

MWB_Report.txt

That block is related to Chrome, lets go for a clean install, see if that stops the blocks totally: If your Chrome Bookmarks are important do this first: Go to this link: http://www.wikihow.com/Export-Bookmarks-from-Chrome follow the instructions and Export your Bookmarks from Chrome, save to your Desktop or similar. Note the instructions can also be used to Import the bookmarks..... Continue for a clean install: Download Chrome installer and save to install later: https://www.google.com/intl/en_uk/chrome/browser/desktop/index.html https://www.google.com/intl/en_usa/chrome/browser/desktop/index.html Next, Open Chrome and sign into your account, open a new tab and type or copy paste chrome://settings/syncSetup hit enter... In the new window that opens "Sync everthing" will probably be selected, scroll down to and select "Managed sync data on Google Dashboard" A new window will open, scroll down to and select "Reset Sync" that will clear synced data from Google Server... Continue to next step to completely Uninstall Chrome.... Next. Uninstall Chrome: https://support.google.com/chrome/answer/95319?hl=en-GB follow those instructions, ensure the option to "Also delete your browsing data" is selected. <<--- Very important!! Navigate to C:\Users\Your user name\Appdata\Local from that folder delete the folder named Google (you will need to show hidden files/folders to see the folder Appdata) For XP that will be My Computer > C:\ Documents and Settings\Your User Name\Application Data\Roaming How to show hidden files and folders for windows: http://www.howtogeek.com/howto/windows-vista/show-hidden-files-and-folders-in-windows-vista/ Next, Install Google Chrome : Next, Import your Bookmarks... (instructions in the first step) Next, Install uBlock Origin for Chrome: https://chrome.google.com/webstore/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm?hl=en Does that help....? Thank you, Kevin

[djlane1]

Thanks Kevin,

I'm not seeing any blocked website notifications from MWB any more.

uBlock blocked 4 requests according to the attached.

 

cheers

Those blocks by uBlock Origin are not unusual when you visit even trusted websites, I have a block showing here at Malwarebytes website for "googletagmanager.com" some sites will have other nuisance entries. Those entries are not malcious per se, they are supposed to help us but do monitor our actions, and so on...

Uninstall Sophos AV http://www.askvg.com/how-to-completely-uninstall-remove-a-software-program-in-windows-without-using-3rd-party-software/ Also delete this folder if still present: C:\ProgramData\Sophos Next, Download "Delfix by Xplode" and save it to your desktop. Or use the following if first link is down: "Delfix link mirror" If your security program alerts to Delfix either, accept the alert or turn your security off. Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator Make Sure the following items are checked:   Remove disinfection tools <----- this will remove tools we may have used. Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created. Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection Now click on "Run" and wait patiently until the tool has completed. The tool will create a log when it has completed. We don't need you to post this. Any remnant files/logs from tools we have used can be deleted… Next, Run Windows Disk Clean Up Utility - https://neosmart.net/wiki/disk-cleanup/ Read the following links to fully understand PC Security and Best Practices, you may find them useful.... Answers to Common Security Questions and best Practices Do I need a Registry Cleaner? Take care and surf safe Kevin...
